Discovery of the day
An international workshop convened in London, Canada in 2025 has outlined a roadmap for developing a multimodal “biotypic” biomarker profile capable of detecting underlying ALS–FTD pathobiology years before clinical phenoconversion, based on the shared TDP-43 proteinopathy that unifies this disease spectrum. Rather than relying on a single biomarker, the proposed profile integrates markers of pathobiology with genetic risk susceptibility profiles and sensitive indicators of genomic and cellular aging to identify when the disease process becomes active across the ALS–FTD continuum. For your focus on clinically actionable diagnostic assays, this framework underscores the necessity of correlating emerging protein biomarkers with multimodal data streams — including imaging and genetic risk architectures — to achieve the preclinical sensitivity required for timing disease-modifying interventions in neurodegenerative disorders.
